My project was to remove the old deck and install a new deck with stairs and railings. Glenn and his company did great craftsmanship and analysis of necessary work. He is very efficient and timely. I will definitely be using him for future home repairs and projects!!!--Regina

Glenn is knowledgeable,professional and a really nice guy. He responded immediately and came when he said he would. His price was more than fair. Orlando, who works for him, is thorough and hard-working. He stood on that roof as if he were the ground. When they were finished cleaning the moss off our roof it looked like new. They power-washed part of our house that needed it while cleaning up the residue from the job. They did great work. We will recommend Glenn and hire him again for other jobs.

Glenn is extremely easy to work with and very accommodating. His work is very meticulous which is key for me. Response time was pretty much immediate after sending an e-mail or placing a phone call. He is extremely trustworthy. I will definately use Phase One Construction for future work. I can't say enough nice things about him. I would recommend Glenn 100%.
